Cloud Secure Edge Integration with SonicOS

Cloud Secure Edge (CSE) offers two edge deployment models to access your organization’s private resources: Self-hosted Private Edge and Global Edge Network. SonicOS 7.1.2 and later supports the Global Edge Network deployment type. With this new capability, any organization can deploy SonicOS 7.1.2 as a Cloud Secure Edge Connector. The Connector is a dial-out connector that establishes a secure tunnel with CSE’s Global Edge Network. It can be deployed in any location with connectivity to your internal services. There will be no change to the control plane. The Cloud Command Center always delivered as a cloud Software-As-A-Service (SaaS) offering. For more information on Cloud Secure Edge, refer to the CSE documentation.

To use the CSE feature, the user must do the following:

1.  Provision a trial or purchased CSE product in MySonicWall (creates an organization). Refer to the section Activating Cloud Secure Edge in MSW.
2. Enable the CSE Connector on a firewall running SonicOS 7.1.2 or higher. Refer to the section Configuring Cloud Secure Edge.
3. Configure Private Access: SonicOS needs to publish the networks, IP Addresses, and Private Domains (optional) for the CSE clients. Refer to the section Configuring Cloud Secure Edge in SonicWall Firewall.
4. Configure access control rules in the CSE (not on the SonicWall firewall). Refer to the section Configuring Access Control Rules on the CSE Console.
5. Enable the Connector. Refer to the section Configuring the Connector.
6. Manage Connectivity: To show the status of TSR, Packet Capture, and Logs. Refer to the section Viewing Cloud Secure Edge Connector Log events

Benefits of Using Cloud Secure Edge

The following are the user benefits of using the Cloud Secure Edge with SonicWall firewall.

• Leverages the SonicWall firewall to enable ZTNA and CSE service.

• Empowers partners to provide robust security.

• Meets the evolving needs of customers.

• Adapts to the demands of various environments.
  The Cloud Secure Edge “Connector” technology into our next-generation firewalls provides unparalleled security benefits:

• Trust no One, Always Verify: With a zero-trust approach, organizations can reduce the attack surface and prevent unauthorized access attempts, even if a device breaches the network perimeter.

• Simplified Remote Access: Cloud Secure Edge Connector (CSE) integration in SonicOS 7.1.2 allows employees to securely access authorized applications from anywhere, on any device, without having to deal with repetitive and complex VPN and Access Policy configurations. With CSE, all user and device level access policies are defined in the cloud command center.

• A Better User Experience: Enabling ZTNA has never been easier. Secure access can now be enabled with a few clicks and a simple private resource definition on your SonicWall firewall.

Connector Concepts

The Connector is a dial-out connector that establishes a secure tunnel with the Global Edge Network. It deploys
in any location that has connectivity to your internal services. Each Connector only connects outbound and does not need any inbound open ports to operate correctly.

The CSE Connector for SonicOS firewall allows secure remote access to private resources behind the firewall. CSE infrastructure enforces access control, not by the SonicOS firewall. Traffic ingresses SonicOS via WireGuard tunnels from CSE POPs. Only inbound access (WAN to protected zones from a firewall perspective) is allowed. SonicOS Group Address Object is created automatically (per Connector). The firewall admin configures the allowed private IPv4 addresses (Group address object) and private domains, if any, that SonicOS firewall needs to resolve for the CSE clients. The Connector establishes a WireGuard tunnel to CSE POPs.

Viewing Cloud Secure Edge Connector Log events

This chapter provides viewing the log events for CSE Connector.

On the SonicWall firewall, navigate to Device > Log > Settings.

Users can view a new log category “Cloud Secure Edge”, and the implementation of New CSE Events such as CSE Connector, CSE Enabled, CSE disabled, CSE Connector Error, CSE Connector Enabled, CSE Connector Disabled.

The CSE Enabled/Disabled event have the date/time, and nominal string fields to indicate status.

CSE Connector Enabled/Disabled have the date/time, and the Connector name in the string field.

CSE error event is logged after exhausting retries to communicate with LM or CSE Command Center or on receiving an error indication from LM (For example: Organization is not created).

The WireGuard module implements WireGuard tunnel log events, and it has sufficient logs to report events on WireGuard packet handling.
SonicOS’s existing support for sending configured log events to an external server should already cover the sending of log events to NSM.
Summarized Connector status can be set in Heartbeats. (0 = all tunnels up, 1 = some tunnels up, 2 = all tunnels down).

Use Case

This section provides the use case information for the Cloud Secure Edge.

Topics:

• Firewall is RMA
• Firewall is a Secure Upgrade
• SonicWall Active/Standby HA Pair Scenarios
• Temporarily Turning off the Connector
• Synchronize Status of the Connector

Firewall is RMA

The old unit continues working for two weeks as per RMA expectations. The user receive a replacement unit and then register to start using the new unit. SonicOS running in the new unit will request LM for a new Connector. LM follow the same process as requesting a new Connector for a firewall.

Firewall is a Secure Upgrade

Users may need to create a new service tunnel and access control policies on the CSE command center.

SonicWall Active/Standby HA Pair Scenarios

Only the primary in an HA pair environment have a Connector created in CSE. The secondary expects to use the same configuration when it becomes the ‘active’ in the active/standby pair and connects with the same variables via WireGuard to the POPs.

Temporarily Turning Off the Connector

Once the user enables the toggle for the Cloud Secure Edge Connector, a new option enables by default. The Enable Cloud Secure Edge connectivity option can be toggled OFF to disconnect the Connector on the firewall. Toggle back enable the Connector again. In this scenario, the Connector remains connected in the CSE console. Do not delete the Connector in the CSE console.

Synchronize Status of the Connector

Request this option in the CSE Status tab, and click it to get the Connector details, including the Connector status from LM. This will help to synchronize the Connector status with LM.
